- SNOW-PLOW.

To all whom it may concern:

Be it known that I, HOWARD GRIMES, of Newcomb, in the county of Essexand State of New York, have invented certain new and useful Improvementsin Snow-Flows; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to improvements in snow p1ows,-the object of theinvention being to so construct a snow plow that it will operateeffectually to raise the snow and discharge the same laterally atrespective sides of the roadway when the plow is moved along the centerof the roadway.

A further object is to provide simple and efficient means for mountinginclined plow boards upon runners and for effecting the adjustment ofsaid plow boards on the runners and relatively to the ground.

With these objects in view the invention consists in certain novelfeatures of construction and combinations of parts as hereinafter setforth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view of a snow plowembodying my improvements. Fig. 2 is a bottom plan view. Fig. 3 is alongitudinal sectional view. Fig. 4 is a transverse sectional viewshowing the wings 17 detached, and Fig. 5 is a sectional View 011 theline a:m of Fig. 1.

1, 1, and 2, 2, represent a series of four parallel runners suitablyspaced apart and braced at intervals by means of a series of cross-bars5 set in notches in the upper edges of the runners. The two outerrunners 1, 1, are provided near their rear ends with shoes or plates 6which depend slightly below the lower faces of said runners and serve toprevent the machine from undue lateral move ment when in use. Theforward ends of the outer runners 1, 1, are made with upper beveledfaces 7 on which the forward portions of plow boards 8 are mounted.These plow boards incline both rearwardly and laterally and theirforward portions near their meeting edges are made with elongated slots9 through which the forward ends of the intermediate runners 2, 2,freely pass. The forwardly projecting ends of the runners 2, 2, wherethey are disposed over the plow boards are provided with suitableSpecification of Letters Patent.

means for the attachment of a tongue 10,- the latter being provided withattaching means for draft animals. The rear portions of the inclinedplow boards are supported upon the beveled upper edges of an upright 11secured upon the runners and extending transversely across the same andbeyond the outer runners 1, 1. This upright is located at the forwardend of a platform 12 secured upon the rear portions of the runners 1-2and is braced centrally by means of a rod 13 secured at one end to saidplatform and at the other end to the upright in proximity to the apex ofthe latter.

At points intermediate of their ends, de flector boards 14 are securedupon the plow boards 8,each deflector board extending from the inneredge of the plow boards to the outer edge of the latter adjacent to therear end thereof and the forward ends of the two deflector boards arebeveled so as to come close together in line with the longitudinal axisof the machine and with the m eeting point of the plow boards. Thesedeflector boards may be strengthened by means of battens 15 and braces16 connecting said battens with the plow boards as clearly shown inFig. 1. Adjustable wings 17 extend rearwardly from the rear ends of thedeflector boards and are hinged to the rear battens 15 on said deflectorboards. Each wing 17 has hinged thereto, an arm 18, the free end ofwhich is provided with a depending member or pin 19 which may beinserted in any one of a number of sockets 20 in the platform so thatthe wings may be disposed at any desired angle with relation to thedeflector boards.

From the construction and arrangement of parts above described it willbe observed that the forward cutting ends of, the plow boards may bedisposed approximately in alinement with the lower edges or faces of therunners and in fact by adjusting these plow boards longitudinally, theirforward cutting ends may be disposed in a plane somewhat below that ofthe bottom faces of the runners. The passage of the forward ends of theintermediate runners 2, 2,

through the elongated slots in the plow,105

the plow boards longitudinally. I therefore secure to the under face ofeach plow board a grooved guide block 21 to receive a guide rib orflange 22 on the adjacent runner 2. For the purpose of retaining theouter portion of the plow boards in proper place and guiding the same, arod 23 is secured at one end to a suitable bracket on each outer runner1 and at the other end to the upright 11 and perforated brackets 24secured to the plow boards move freely on the rods 23.

A lever 25 is .pivotally attached at its lower end to each outer runner1 near the rear end thereof and passes upwardly through the platform,for which purpose the platform is provided with elongated slots 26. Thelevers 25 are connected with the respective plow boards by means of rods27. By means of these levers the plow boards can be moved longitudinallyso as to change or adjust the relation of their forward cutting ends tothe ground and cause them to cut more or less deeply into the snow asoocasion may require. Each of the plow boards may be retained in theposition to which it may be adjusted by means of a pin 28 passingthrough any one of a series of holes 29 in said plow boards and engagingthe upright 11.

Slight changes might be made in the details of construction of myinvention without departing from the spirit thereof or limiting itsscope and hence I do not wish to restrict myself to the precise detailsherein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is,

1. In a snow plow, the combination with a series of runners and a framethereon, of a plow board slidably mounted in an inclined position onsaid framework and runners and having its cutting edge in advance ofsaid runners, and means for sliding said plow board forwardly andrearwardly.

2. In a snow plow, the combination with a series of runners andframework thereon, of two plow boards slidably mounted on said frameworkat an inclination relatively to the runners and relatively to eachother, the forward cutting edges of said plow boards projecting beyondthe runners, and means for adjusting said plow boards forwardly andrearwardly.

3. In a snow plow, the combination with a series of runners andframework thereon, of a plow board slidably mounted on said framework inan inclined position and having its cutting edge disposed in a plane below that of the top of the runners, and means for moving said plow boardforwardly and disposing its cutting edge in a plane below that of thebottom of the runners.

4c. In a snow plow, the combination with a series of runners, ofinclined plow boards mounted on two of said runners and having slotsthrough which other of said runners pass for the attachment of draftdevices, and means connected with the runners and with the plow boardsfor adjusting the latter with relation to the runners and to the ground.

5. In a snow plow, the combination with two pairs of runners, of plowboards mounted upon one pair of runners, the other pair of runnersprojecting through said plow boards near the forward ends of the latter,means for supporting the rear portions of said plow boards, one pair ofrunners and said support being adapted to retain the plow boardsinclined with relation to the runners and with relation to each other,means for adjusting the plow boards longitudinally, and means forretaining the plow boards in the positions to which they may beadjusted.

6. In a snow plow, the combination with a series of runners and inclinedplow boards mounted thereon, of deflector boards secured upon the plowboards and disposed at an angle to each other.

7. In a snow plow, the combination with a series of runners and inclinedplow boards mounted thereon, of deflector boards disposed at an angle toeach other and secured upon the upper faces of the plow boards, wingshinged to the rear ends of the deflector boards, and means for adjustingthe positions of said wings.

8. In a snow plow, the combination with a series of runners, plow boardssupported by the forward portions of the runners and a platform on therear portions of the runners, of deflector boards disposed at an angleto each other and secured upon the upper faces of the plow boards, wingshinged to the rear ends of the deflector boards, and arms hinged to thewings and adjustably connected to said platform.

9. In a snow plow the combination with a series of runners, and inclinedplow boards supported thereby, of deflector boards disposed at an angleto each other and secured upon the plow boards, and means for movingeach plow board and its attached deflector board forwardly andrearwardly.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
